PRD-5183 - Enable basic crosstab editing. When editing crosstabs, we preserve dimensions if they have not changed, and facts if the
 complete fact configuration has not changed.
[CLEANUP] - Disable performance tests during the fast run, only enable when long-running tests run and only if
 there is no cobertura active (as cobertura slows everything down, why run performance tests on a slowed system?)
PRD-5183 - Fixed test case after making crosstab element contain crosstab groups.
[CELANUP] - Re-enabled tests.
